this is politics. >> listen, we know what change looks like, madison, and what he's selling ain't it. giving more power back to the biggest banks, that's not change. another $5 trillion tax cut that favors the wealthy is not change. >> reporter: there are two keys to victory for obama this time around, first is dedication, he needs crowds not to so much fall in love with him again but to grip down and get out that vote and to do that he needs the young people, the american electorate of tomorrow. there are 39,000 students at the university of wisconsin and in this state they can register to vote up to election day. why did you vote for him? >> well, i'm gay, so that is a big pull for me. romney is very anti-gay marriage and obama, since he came out and supported gay marriage last spring, that's one of the big things for me. >> reporter: the other key for obama, well, it's victor schmidt and so many like him.
